Our manuscript on dynamic pricing schemes in bi-demand markets is now available on arXiv, see http://arxiv.org/abs/2107.05131. In contrast to static models, the dynamic setting allows to update the prices between buyer-arrivals, therefore it is capable to achieve maximum social welfare without a central coordinator. Continuing the work of Cohen-Addad et al. and Berger et al., the paper focuses on multi-demand markets. In particular, we provide an optimal dynamic pricing scheme when the demand of each buyer is at most two.
